In the early days of the post-Soviet era, the Russian government actively used public service advertising to establish a new identity. Unlike the provocative public service advertisements of the Soviet era, which were mainly used to promote the government’s ideology with a strong ‘propaganda’ tendency, the public service advertisements in the post-Soviet era serve to make the public aware of the various social problems facing Russia. The public, recognizing the related problems through public service advertisements, will have empathy for the solution and improvement of the problem. And based on this, the foundation for the modern Russian identity is established. Therefore, it can be said that modern Russian public service advertisements represent the current state of Russian society and Russian identity. This article outlines the flow and history of public service advertisements in Russia since the 2000s, and furthermore, the aspects and characteristics of changes in various materials and issues appearing in advertisements. Through this, we examine the changes in the production method and expression of public service advertisements in Russia since the 2000s. In addition, this paper analyzes Russian perceptions and their attitudes toward major social issues that have been continuously exposed through public service advertisement channels over the past 20 years. The various values and problems presented by modern Russian public service advertisements are directly or indirectly related to the tasks that must be preceded for Russia's future, which will ultimately change more positively and progressively than the present. In this respect, the various messages that are continuously spread to the Russian people through public service advertisement channels can be seen as an indirect suggestion of the Russian identity that is ‘being created’ as well as the identity of Russia that is ‘to be created’. In addition, various messages and images seen through Russian public service advertisements can be seen as one of the important tools for realizing the ‘post-Soviet Russian identity’ that the Russian government is trying to establish.

This research was performed to get the informations needed to manufacture fermented milk products using bifidobacteria as starter culture. The conversion of constituents in the whole milk fermented by Bifidobacterium bifidum ATCC 11863 was investigated, and the results were compared with those by several lactic acid bacteria generally used for the fermented milk products. 1. The use of lactose varied according to the kinds of bacteria, such as B. bifidum, L. acidophilus, L. casei and S. thermophilus. When the whole milk was fermented by B. bifidum, the glucose reached 480 mg per 100 ml; while galactose reached 661 mg per 100 ml when S. thermophilus was grown in whole milk. 2. B. bifidum and L. acidophilus raised the, soluble nitrogenous compounds in whole milk after 24 hours at 37℃, however, there was little change soluble nitrogenous compounds content of whole milk by L. casei and S. thermophilus. 3. The content of free amino acids was increased by B. bifidum and L. acidophilus after 24 hours at 37℃; whereas decreased when L. casei and S. thermophilus were grown. 4. The polyacrylamide gel electrophoresis evidenced no significant change of casein but distinct changes of whey protein were observed by B. bifidum, L. acidophilus, L. casei and S. thermophilus at 37℃ after 24 hours. The change of whey protein was more noticeable when whole milk was fermented by L. acidophilus and L. casei than by B. bifidum and S. thermophilus. 5. The pyruvic acid content was decreased in whole milk after 24 hours at 37℃ by B. bifidum, L. acidophilus, L. casei and S. thermophilus. Lactic and succinic acid were produced during the fermentation of whole milk by B. bifidum, L. acidophilus and L. casei but B. bifidum produced less lactic acid than other bacteria. 6. Acetic acid was increased in the whole milk by B. bifidum, L. acidophilus and L. casei after 24 hours at 37℃. It was increased more rapidly by B. bifidum than by other bacteria; however, it was decreased during the fermentation by S. thermophilus. When B. bifidum was grown in whole milk, volatile organic acids such as propionic, isobutyric, butyric, isovaleric, valeric and caproic acids were decreased.

本 試驗에서는 中部以南 全域에서 蒐集한 一般農家栽培種, 命名된 在來品種, 野生種, 美國, 臺灣, 越南에서 導入한 品種, 그리고 野生種과 栽培種間의 交配後代에 對한 種實重의 變異를 調査하였다. 1. 農家傳來種의 種實重의 分散은 뚜렸한 2個의 頂點을 갖이는 曲線을 그리고 있으며 이는 우리나라 現在 大豆를 크게 두個 集團으로 區分해 볼 수 있음을 나타내는 것으로 그 平均 百粒重은 各各 12g와 24g 이었다. 2. 農家傳來種의 分布를 보면 南部地方에는 小粒種이 많이 栽培되고 있고 中部地方에서는 大粒 乃至中粒種이 栽培되는 傾向을 알 수 있었다. 一般的으로 우리나라 大豆는 外國種에 比해 大粒型이 많이 栽培되고 있으며 全國에서 蒐集한 500餘種에 對한 平均百粒重은 22.2g이었으며 最高 44.8g서부터 最低 6.2g까지였다. 3. 우리나라 栽培種의 最低 百粒重 6.2g는 野生種中間型 百粒童 7.4g보다 작았다. 野生種과 栽培種間의 交雜은 容易하였으며 F₁와 F₃의 種實重은 兩母品種 사이에 分布하였으며 F₂의 一粒重 平均은 兩親의 幾何平均에 近似하였다. This investigation was conducted to determine the variation of seed weight for land races, local named varieties, wild type collections, some introduced varieties, and F₂and F₃generations of a cross between cultivar and wild type of soybeans. Land races currently grown by farmers were consisted with distinctly different two groups and averages of seed weight of the groups were 12g and 24g respectively. In general, the soybenan seeds grown in southern part of Korean peninsular were smaller than the seeds collected in middle part of the peninsula. The cultivars grown in Korea are relatively large in seed size in comparison with the varieties grown in other countries. The seed weight of the collected land races ranged between 44.8 grams per 100 seeds and 6.2 grams and the average weight was 22.2 grams. Seed weight of F₂and F₃generations of a cross between wild and intermediate type ranged between parents and the average weight per seed of F₂generation was close to the value of geometric mean of the parents.
한국원자력연구원 내 지하처분연구시설 주변의 암반 손상대 영향 평가

지하구조물의 굴착을 위한 발파 충격과 굴착후 응력의 재분포에 의해 발생하는 암반 손상대(Excavation Damaged Zone, EDZ)의 발생은 구조물의 장기적 안정성·경제성·안전성에 영향을 미친다. 본 연구에서는 조절발파기법으로 굴착된 한국원자력연구원 내 지하처분연구시설에서 굴착 후 발생하는 손상대 규모 및 특성을 측정, 분석하였으며 이를 모델링에 적용하여 손상대가 터널의 역학적, 수리적 거동에 미치는 영향을 평가하고자 하였다. KURT에서의 손상대 현장시험을 통해 1.5m의 손상구간을 확인할 수 있었으며 Goodman jack 시험과 실험실 암석실험을 통해 암반의 물성은 발파전 물성에 비해 대체적으로 50% 정도 변화함을 알 수 있었다. 이러한 암반 손상대 크기와 물성변화를 모델링에 적용하여 수리-역학적 연동해석을 실시하였다. 손상받지 않은 구간에 비해 손상대의 변형계수는 50% 감소하며 수리전도도는 1 order 증가하는 것으로 가정하였다. 해석 결과 손상대를 고려하는 경우 변위는 증가하고 응력은 감소하며 지하수 유입량은 약 20% 정도 증가하는 것으로 나타났다. The development of an excavation damaged zone, EDZ, due to the blasting impact and stress redistribution after excavation, can influence on the long term stability, economy, and safety of the underground excavation. In this study, the size and characteristics of an EDZ around an underground research tunnel, which was excavated by controlled blasting, in KAERI were investigated. The results were implemented into the modelling for evaluating the influence of an EDZ on hydro-mechanical behavior of the tunnel. From in situ tests at KURT, it was possible to determine that the size of EDZ was about l.5m. Goodman jack tests and laboratory tests showed that the rock properties in the EDZ were changed about 50% compared to the rock properties before blasting. The size and property change in the EDZ were implemented to a hydro-mechanical coupling analysis. In the modeling, rock strengths and elastic modulus were assumed to be decreased 50% and the hydraulic conductivity was increased 1 order. From the analysis, it was possible to see that the displacement was increased while the stress was decreased because of an EDZ. When an EDZ was considered in the model, the tunnel inflow was increased about 20% compared to the case without an EDZ.
